The sludge buffer tank was suffering from through wall corrosion at the vapour interface level. The tank could not be taken offline for an extended time which traditional repair methods would require due to demand. Any repairs would have to be carried out without hot work or the use of mechanical equipment due to the risk of sparks.
Sludge buffer tank fabricated from glass coated mild steel.
After cleaning and degreasing the surface, it was prepared by hand. The repair plates were pre-coated with Belzona 5831 and bonded over the through wall defects using Belzona 1161. Finally, Belzona 5831 was applied to the entire repair area.
The customer had only been able to run the buffer tank at a reduced capacity of 65%. No other alternatives were deemed to provide a viable solution to the customer’s requirements. Belzona solution kept the site running with minimal disruption and was carried out without hot work or the use mechanical equipment, hence presenting no risk of sparks.
The application was inspected in 2015 and found to be in perfect condition.
